Member Function Documentation

static final String com.graeff.pwencode.MD5Crypt.crypt ( String  password )

static

This method actually generates a OpenBSD/FreeBSD/Linux PAM compatible md5-encoded password hash from a plaintext password and a salt.

The resulting string will be in the form '$1$<salt>$<hashed mess>

Parameters

password

Plaintext password

Returns

An OpenBSD/FreeBSD/Linux-compatible md5-hashed password field.

static final String com.graeff.pwencode.MD5Crypt.crypt ( String  password, String  salt  )

static

This method actually generates a OpenBSD/FreeBSD/Linux PAM compatible md5-encoded password hash from a plaintext password and a salt.

The resulting string will be in the form '$1$<salt>$<hashed mess>

Parameters

password	Plaintext password
salt	A short string to use to randomize md5. May start with $1$, which will be ignored. It is explicitly permitted to pass a pre-existing MD5Crypt'ed password entry as the salt. crypt() will strip the salt chars out properly.

Returns

An OpenBSD/FreeBSD/Linux-compatible md5-hashed password field.
